Subject:   ICH9 panic/instability on recent kernel

Hi,

I have a core-2 system with a 3ware SATA RAID controller for the main 
disks and the built-in Intel ICH9 4-port SATA controller that is only 
used for the DVDR.  An 8-STABLE kernel csup'd and compiled on April 25 
works fine on this system.  Kernels from source csup'd this week are 
extremely unstable and usually panic or hang just minutes after booting. 
  The following warning messages appear after the kernel probes the SATA 
controller and/or ICH9 USB controller and continue about once per 1-2 
seconds until the system crashes:

May 13 14:21:05 sonicyouth kernel: unknown: WARNING - ATAPI_IDENTIFY 
requeued due to channel reset LBA=0

Disabling the ICH9 SATA controller in the BIOS allows the system to boot 
and run normally.

Changes were made on April 28 to allow better support for 6-port ICH9 
controllers (SVN rev 221156) and I am wondering if my controller is now 
being incorrectly recognized.

Here's the relevant kernel messages:

controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x1c4

If I csup the most recent kernel sources, I get the same problem. 
However, if, after csuping the latest kernel sources, I then fetch the 
version of sys/dev/ata/ata-all.c as of April 27, everything works fine. 
  Here's the output of pciconf -l:
